Out of interest what is the data stream that is predicting it taking until 2023 for traffic to recover to 2019 levels?
How are Airlines projecting 40%, 60% etc traffic levels in 2021?
That article may be bang on, it could be incredibly wide of the mark... Right now it is completely unknown! There has been no global situation like this before.
Airlines may be over pessimistic right now, which is understandable with little or no revenue for the past 12 weeks... You certainly could argue a late summer bounce back may be on the cards in certain sectors ( IF Governments get their acts together and work on sensible solutions ).
